Detailedly analyzing kinetic origins reveals that size-controlling would bring about lowered charge transfer resistance and quicken ions diffusion. Even at 5.0 A g −1, a considerable capacity of 682 mAh g −1 is remained. Among them, MoS 2-1 μm delivers an initial charge capacity of 904 mAh g −1, reaching up to 1,337 mAh g −1 over 125 loops at 0.1 A g −1. Utilized as LIB anodes, size-tuning could serve crucial roles on the electrochemical properties. The effective tailoring process further induce various sizes (5, 2, 1 and 90 nm) of sheets, accompanying with the increasing of active sites and defects. Through the hydro-refining process of raw molybdenite ore, containing crushing–grinding, flotation, exfoliation, and gradient centrifugation, 2D molybdenum disulfide (MoS 2) with high purity is massively obtained. The pursuing of natural electrode resources with high lithium-storage capability has triggered a plenty of activities. Restricted by the dissatisfied capacity of traditional materials, lithium-ion batteries (LIBs) still suffer from the low energy-density. 3State Key Laboratory of Powder Metallurgy, Central South University, Changsha, China.
